What is Thermal Hydrolysis?

So you want to know, what is the thermal hydrolysis process? Thermal Hydrolysis is a chemical process in which the organic molecules (in the substrate/ feed material) are split into two parts by the addition of a molecule of water. The process forces the water molecules between the chemical bonds holding together large tissue molecules […]
